A video of an 84-year-old man who appears to be moving objects with only his internal energy has become viral in China. The man also slices his stomach with a cleaver but remains unscathed.

The power of Qi is often demonstrated in various styles of Chinese martial arts most often practiced by Buddhist monks. You’ve probably seen those Shaolin shows where they make their bodies immovable or unraisable, and even immune to the sharp tip of a spear, but an 84-year-old man from China takes things to a whole new level. He claims he can channel his inner Qi (Chi) to move and even break various objects. To prove his ability he allowed a camera crew to record several of his feats, including moving bricks and a bowl full of water and breaking a glass bottle. The video of him performing these extraordinary stunts has been doing the rounds for about two years, but so far no one has been able to explain just how he’s doing it.
